As expected, during the Intel opening keynote at Computex 2015, Kirk Sakugen, SVP of Intel took the time to express Intel's vision of the wearable platform and while doing that he also sneaked in the official announcement of Thunderbolt 3. This new interface is probably the biggest change since Intel first announced Thunderbolt 1 in 2011.

Thunderbolt 3, will be coming to devices later this year and the new 40Gbps speeds is not the most radical upgrade but the choice to implement it on the new USB Type-C connector is definitely a big difference. Moving forward from the miniDP connector previous Thunderbolt interfaces featured, Intel's choice to go with the new USB Type-C connector ensures future proofing the interface.
As devices goes thinner, companies often just do away from including big ports on their device. Just take a look at the MacBook which only has one port which can do everything from outputting to a monitor to juicing up the device.

Whilst implementing the new Thunderbolt interface into the USB Type-C connector, Intel didn't drop any features of the existing connector and it's still capable of powering devices and display out content to a monitor. Besides being a ferrari for file transfers, Thunderbolt 3 is also capable of beaming out dual 4K 60Hz monitors without breaking a sweat.

From the looks of it, USB Type-C is the future of any mobile device and aesthetically, the new Thunderbolt 3 connector is identical to that of a standard USB Type-C and the difference is the lightning bolt icon.
